I've read this article regarding Send mail from Multiple devices/application
Option 1 is the MS 'Recommended' one - but then there's this kind of "disclaimer" in the bottom:

Are the IIS option considered as the 'best solution' in 'relaying' towards O365?
Looking for the 'Best' solution possible - security-wise
